So if you don’t mind spending about $5 a month, I’d recommend buying the monthly pass that allows ad skipping. That will also get you unlimited “raids” on stages you’ve beaten, thus allowing you a faster farm on those stages without having to waste time grinding through them. That said, I’d probably time that monthly pass out with the other monthly things that way it’s all on the same rotation. Aside from all of that, this game is super grindy. If you’re familiar with playing WoW, then think of what the drop chance of getting the raid legos in the current content of WoW, and that’s the kind of grind you need just to get a single gem that still won’t be enough to help you pass a level. And then understand that there are even rarer gems within the same rank that have even lower chances of dropping. Or just spend thousands of dollars and you’ll be able to push through a few levels that way as well because that seems to be what it takes to get anywhere in this falsely advertised game.
